Is moving a personal account to a different country an insanely obscure edge case?
Because I tried to do that recently with O365 and I literally couldn't move my subscription without killing the old one and creating a new one.
Every other software service I use somehow managed to make it easy: fill in the new billing details. Done.
But not Microsoft. Billing and fulfilment details are on different pages, there's no obvious way to get from one to the other, and if you want to change country you can't.
Superb.
